No. Both GNOME ("Open with"/"Preferred programs") and KDE 4 edit the file directly; Gconf is generally not used anymore for file type associations.

See the "MIME Actions specification" on freedesktop:

"application/x-extension-html" probably means all files having the '.html' extension, regardless of automatically-determined MIME type. (For example, if you rename a .jpeg file to .html, it will *still* be detected as image/jpeg, but matching by extension will take priority.)

"userapp-*.desktop" files are created when you manually specify the path to your program in the "Open With..." window (the 'other' choice).
